LAB TRIBUNE | July 2010 Product Review 3E AD The paste is always used when larger amounts of material (bars, pontics, etc.) need to be applied quickly. It can be combined with primopattern gel without any problem. For example, with bridge frameworks where the copings of abutment teeth have to be mod- eled first using primopattern gel, light cured and then prepared. The pontic, which is fabricated using primopattern LC paste, is then simply placed between the finished copings (Fig. 8). The con- nectors can then be adjusted using gel, if required (Fig. 9). The gel ensures a good connec- tion between both the polymer- ized copings and the paste. Addi- tional areas of application for the combined use of paste and gel are: • All types of implant work. • Frameworks for zirconia copy milling machines. • Tertiary frameworks over elec- troformed mesostructures. • Frameworks for electroformed bridges. Generally, primopattern can f LT page 1E g LT page 4E Fig. 4: The pattern is modeled very quickly because it is not necessary to pause. Fig. 5: It can be modeled in one step. Fig. 6: If the surfaces of the primary cop- ings have been polished to a high luster, a correspondingly perfect inner surface of the secondary crowns is attained. Fig. 7: primopattern LC paste is always used when larger amounts of material have to be applied effi- ciently. Fig. 8: The modeling paste is very practical not only in the case of pon- tics but also with bar segments, posi- tioning templates or placement aids. Fig. 9: The connectors can also be adjusted using gel, if required.
